20 inch with 75 gr v max.
Really happy with barrel. Bought 2 boxes of hornady black 105s that shot a little over moa. Loaded up some 75 gr v max with Varget and shooting half inch groups at 110 yards. No complaints. I bought the barrel to be a night gun and was hoping it would shoot the lighter stuff good. I would buy another.
Looks Great No Machine Marks
Not sure what happened with the other reviewer, but after careful bore inspection and review of the M4 feed ramps, I have come to the conclusion that this was a very well made barrel as I have come to expect from Faxon. Absolutely no feeding problems what so ever, and as for accuracy, I will have to update as soon as I get to the range. The QC seems spot on with the barrel I received as well as the markings made (as commonly seen with Faxon barrels) on the barrel extension to ensure inspection. Thanks to Brownells for offering a high quality barrel at such a great price.
I bought two
Outstanding and very accurate. I liked them so much that I re barreled two of my rifles. For my money Faxon barrels are as good as it gets, the combo of Stainless and nitride in a buttoned barrel is perfect.
Excellent Shooter
With the larger AR rounds (AR-10/308) trending towards shorter barrels than we've seen in the past, but the 6.5 staying relatively long made me curious as to how this would hold. Then there's the 1-8 twist. The military contract is for 1-7.5 and 18"barrel. But I was feeling froggy. 1.2" center to center 20mph winds gusting to 30 (shot by a buddy convinced me to take the leap. Barrel is well made, gas port is properly sized, finish is excellent. I don't have the fancy equipment my buddy does but I can tell you at 100 yards almost shot a single hole. If you're looking to get into the long range game at a lower price point, this is it.
6mm ARC barrel
So far Ive only ran a break in routine with the barrel. But the last 5 shots were sub MOA with Hornady Black ammo. The fit was nice and tight in the receiver and the threads were smooth and straight for muzzle device. Feed ramps are proper and Ive had no feeding issues. Good barrel.
not great groups YET
I have shot 7 3 shot groups with this barrel and they were 1.3 -1.8MOA at 100yds with benchrest... not amazing thats for sure(i have 2 other rifles that shot 0.5 moa so its not the shooter) maybe it will get better with handloads? ive been trying the hornady factory 105 black and 108gr match. not sold on this barrel yet, but dies get here soon and will try some lighter gr bullets might be the trick with 1:8 twist. BTW 2550FPS with the hornadys
Gas much?!? Maybe too much...
The overall quality seems to be good; as expected from Faxon. The price was excellent and the 16" length coupled with the 6mm ARC makes for a very potent hunting/tactical carbine. The ammo I've tested so far, both factory and reloads, suggests that once this barrel is properly seasoned it should make for a consistent 1MOA to sub-moa shooter. My only complaints are the mid-gas: which seems to be a bit too much, especially suppressed, and the 1:8" twist rate. A rifle-gas and 7.5" twist would have made an "okay/good" barrel into a "great" barrel. Velocities with Hornady factory 108ELD-M were surprisingly high, at over 2500 ft/s on average: making for a very light and handy carbine that is capable of reaching 1000 yards. The 6mm ARC is a 100% 'YES' for me: the 16" barrel, no-brainer for average use and hunting. Gas length and twist rate choice: I might have gone another way, but it shoots pleasant enough and considering the price, it was worth it. Good barrel for the money, which supports a great caliber!
